Filming at night! Any tips?

Hello!
I am a year 12 media student and as part of my assessment I have to create a short film. Part of it will be filmed at night/low light near in a remote area so lighting is an issue since the only power I will have is my car. I was wondering what are some things I can do to get good visibility? The camera I am using is a Nikon D3200 which may not be the best for filming but its what I have access to! Do I need to purchase a new lense or a type light that runs on a battery that wont ruin the shot? And what the best settings for low light are? I am clueless with this stuff so every bit of help is appreciated! Thanks :)
